The container won't matter, but most broadcast MXF use MPEG compression. That will matter, but there's also not mich you can do about it.
Thank you for the quick response. Along the way I have saved a few segments to "Match Sequence Settings" and I saw that these files output as MPEG. One interesting note, however, is that when combined in a PrPro sequence, the MPEG output is fuzzier and less stable than the output I've been getting with MXF.
So it sounds like -- ProRes > MXF > MXF Wrapper -- is my best bet.
Thanks for the info ....
You're still confusing two issues. ProRes is a codec, MXF is a container. You can have many different codecs in the MXF container, and which codec you use for any given purpose will matter.
If you have exact specifications from the broadcaster as to how you should deliver the content, please post them. That will make if much easier to recommend export settings.
Thanks, Mark ...

MPEG-2 Long GOP
Container: MXF OP1a
We've been shooting to this standard all along, editing the MPEG clips in one- to two-minute subject-related files, and wrapping each in MXF. Now, at the end of the project, I just want to be sure that wrapping all 20 files in one big MXF container is the best way to go.
Okay, so the export settings to use are
- Format: MXF OP1a
- Preset: XDCAMHD 50 NTSC 60i
But I gather that's not really the essence of your query. Rather, if I understand correctly, here's the workflow you describe:
- edit a series of 1-2 minute sequences
- export each chapter to the settings above
- round-trip the resulting exports into PPRO
- collect the chapters in a sequence
- export the big sequence to the same settings.
If I got that much right, then I'd advise Steps 2&3. Instead, nest the sequences from Step 1 into a single sequence. That eliminates the generational degradation that you're wisely concerned about.
Of course, if you want a standalone clip for each chapter, then go ahead and perform Step 2. Just don't round-trip those outputs back into the project for further editing.
Excellent advice, Mark. Thanks for the feedback. I've still got some time, so I'll give both of these suggestions a try. If I screw it up, I'll trust the broadcaster to fix it I
